(1) Gasoline engine oil and diesel oil are generally not common. There are exceptions to this principle, such as FAW Volkswagen Jetta sedans one of the original engine oil can be used for gasoline and diesel Bora Bora on two kinds of cars. However, only in the automobile factory with specific instructions marked oil or gasoline engine is the common oil and diesel, in order to indicate the level of GM.
(2) Selection of the oil viscosity should be appropriate and can not be the preferred choice of the oil viscosity. Some users believe that oil viscosity is, the better the role of lubrication, it is a wrong point of view. Guarantee reliable lubrication in the engine under the premise. Oil viscosity should be as small as possible. Inappropriate choice of high-viscosity oil will increase resistance to the operation of the engine, fuel consumption increases. In addition to the viscosity of the oil used in the summer, apply only to some serious wear and tear of the engine. The same. Do not choose the oil viscosity is too low. Otherwise it will too low oil pressure, oil film strength enough, or piston ring Mifengbuyan. Therefore, according to the status and season to correct choice of engine oil. For oil, a common winter and summer. Can be used throughout the year.
(3) Adhere to the principle of economy. In choosing the use of oil-level, high-level oil can lower the requirements for use on the engine. However, the use of excessive levels of oil will cause waste. Spaces will be low levels of oil in the engine require a higher use, otherwise it will cause engine wear and damage early.
(4) Oil is often used very short period of time will be black color. At this time many users believe that the poor quality oil. In fact, this is usually a normal phenomenon. Engine lubricating oil is not only the role, but also the role of cleaning, it can be attached to the internal engine carbon deposition cleaning scattered down in the replacement of oil, coke can be discharged with the oil. So the event of a short period of time the phenomenon of black oil, should be careful analysis of its causes.
(5) In the engine work, under normal circumstances have oil consumption. The amount is less the issue. General consumption in the run-in period of relatively large. Because the number of different oil consumption, so users should regularly check the oil through the oil-foot-height, found to be inadequate timely added. If a sudden increase of oil consumption, they should check whether there are oil spills, piston rings or valve seal wear it, no matter what reasons. The timely elimination of all checks. In principle. Different manufacturers oil found in different base oil and additives, mixed use in possible or not compatible with the reaction. Therefore, oil can not mix different brands. However, under exceptional circumstances can also be temporary mix, once conditions allow timely replacement of all the oil. Original oil fully meet the needs engine work, if you allow the economic conditions, of course, can choose a higher level of oil. Select oil generally should pay attention to two indicators, the use of First-choice and the second is the viscosity-level choice. In determining the level of oil, should give priority to domestic brand-name oil. Because a lot of informal manufacturers of domestic oil production can meet international standards and are cheap, you can rest assured use.
